• The paper describes the energy dissipation mechanism during beam-plume/plasma interaction. From spectroscopic and other optical measurements of Ti-plume induced by pulsed YAG laser shot, it has been concluded that major energy dissipation processes in plume are ; 1) Absorption of photons in a plume/plasma by Inverse Bremsstrahlung, and 2) Rayleigh scattering of incident beam by ultra fine particles formed in the plume. Both processes have strong dependence on wavelength of radiation and the paper gives the generalized idea of energy loss of laser beam in laser induced plume/plasma.
